I have a 2003 Audi A4 1.8 Turbo around 67,000 miles. It started shooting a lot of white smoke in couple of days. I have read the other answers, and I thought it was burning antifreeze. When I took it to the mechanic shop, the first mechanic said the motor was bad. The second mechanic told me it could be related with turbo. He took the turbo out and yes it was the problem. Turbo was shooting the oil out. Instead of buying an expensive new turbo, I bought the rebuild kit for $40, and rebuilt it. For around $500 the problem is solved. No more smoke , and much better performance. If you have a car with turbo, that might be your problem.
White smoke means head gasket, cracked head or equivelant.
if it is white smoke engine need to rebuilt.
Piston rings or Rich oil .
Head gasket
the smoke that comes out of a exhaust pipe is supposed to be white
bad head gaskets, or a crack in the block or head.
White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.
Black smoke means you're burning fuel, blue smoke, you're burning oil, white smoke, you're burning coolant.
Water vapour due to condensation in the exhaust pipe.
white smoke is coming from my exhaust why?
the "smoke" is always there when you breathe in the morning, when its cold, you see like a mist, that what that is, its just you usually cant see it
usually a blown head gasket (most all the time white smoke on a a diesel engine means antifreeze in the combustion chamber)
